[MapServer-users] cluster points

[Jörg Thomsen (WhereGroup)]

Dear list,

I have a problem with clustering of some points (layer at the end of 
this mail).

As soon as I insert the block
CLUSTER
    MAXDISTANCE 50
    REGION 'ellipse'
END

the capabilities-document [1] of the wms ends abrupt with
>     <sld:GetLegendGraphic>
>       <Format>image/png</Format>
>       <Format>im

so I cannot load it to a client.
getmap/browse-mode [2] works fine.

I don't see the reason, does anyone else do and can tell me?
